1. Mixing
Put the raw materials into the reactor for full mixing to ensure uniform distribution.
2. Melt Processing
The mixed materials are heated and melted through a melt reactor or extruder.
3. Extrusion
The molten material is extruded through an extruder and cooled to form.
4. Cooling
The molten glue is quickly cooled using a water cooling or air cooling system to form granules.
5. Granulating
The cooled glue is cut into uniform granules by underwater granulator.
6. Screening
Use a sieving machine to remove unqualified granules to ensure consistent particle size.
1. Cooling Speed: Underwater cooling speed is fast, which can prevent the material from overcooling or crystallization.
2. Particle Morphology: Due to the better cooling effect of water, the final particles are usually smoother and more uniform, and the particle size can be adjusted by the setting of the control equipment.
3. Cutting Effect: Underwater granulation technology can ensure that the particles are uniform and the edges are smooth, avoiding too many sharp edges of the particles, which will affect subsequent use.
